Application 'liled April 16. 1915. Serial No. 21,653.

To all who/m. it muy] concern f Be it known that l, GUs'rAvn L. Hana, a

. subject of the Emperor of Austria-Hunries a Windin gary, and resident or' the borough of Manhattan. in the city and Stato oi New York, have invented a nenv and useful Hose Clamp, of which the following is a speer lication.

(Ene object of my invention is to provide a hose clamp ivitl; novel means for tightening an enen-Cling band and looking it in its tightened p tion,

Another objectiL to provide a hose Clamp having a coupling to which one end of the encircling band attached and which carinoons on which the other end of the bril wound .tor tightening it..

A further object is to provide a hose riamp in which the winding member is so spaced from the hand that the latter may be Wound around 'the hose any desired number of times bef'm'e tightening it.

Still further objects are to provide a hose rlamp having a coupling and means for re moxablyY 'attaching both ends or a band to the coupling and means for tightening the band and locking it in any desired position; to provide in a hose clamp, a. coupling independentof the band so that it can be used with a band of any desired length; and to provide a hose clamp which can be simply and eliieiently operated and which can be tightened to any desired degree and will withstand great pressare and can be manufactured at a very low cost.

A practical embodiment oi' my invention is represented in the accompanying drawings, in which,

Figure l is a side elevation partly in seotion, ot a connection between a hose and a pipe with my hose clamp attached, Fig. Z

is a section taken in the plane of the line A-A of Fig. l, looking in the direction of the arrows, Fig. 3 is a section taken in the plane of the line B-B of Fig. l, looking in the direction ot the arrows, Fig. l is a detail view in section, showing the method of removably looking one end of the band to the coupling, Fig. 5 is a detail view in seotion, showing the parts in the position which they assume when the band is ready to be tightened, Fig. 5 is a view of one side of the coupling, Fig. 7 is a top plan view of the coupling, Fig. 8 is a View of the other side of the coupling, Fig. 9 is a horizontal section taken in the plane of the line C-C ot' Fig. 7, looking in the direction of the arroivs, Fig. 10 is a view in end elevation oi the coupling with the bolt removed, and Fig. 11 is a section taken in the plane ot the line D-D of Fig. 10, looking in the direction of the arrows.

T he hose clamp comprises a band 1 and a coupling consisting of the slitted back member 2 and the side members 3. The side members 3 have enlarged portions provided with holes 4 adapted to carry the Winding bolt rllhis bolt 5 has a ker 6 in its head which is extended into the body portion of the bolt to form the slot 7, and the othe: end of the bolt has screvv-threads to receive the nut 8. The back member Q is provided with a transverse slot 9, and the. portions of this member adjacent the slot 9, are slightly oil'set from each other, the outer portion having its upper face beveled.

In operation the band l is inserted into the slot 9, as shown in Fig. 4. The offset portions of the back member 8 so distort the band that it will be firmly locked in place against any pull in a direct-ion substantially at right angles to the slot so that When the band is tightened, it will be tirmly locked to the coupling but when it is loosened, it can be readily removed therefrom. When the band has'been thus looked to the coupling,

it may be Wound around the hose as many times as desired,'the Winding bolt 5 being saiieiently spaced from the back member S to allow for any desired number ol? wraps.

he tree end of the band is then inserted in the slot 7, and the bolt turned to tighten the band to any desired extent, after which the nut 8 is tightened to bild the bolt in this position. The nut 8 is preferably a left handed nut so that the pull on the band automatically tightens the nut. The band l may be ot any flexible material which is suitable for this purpose. The offset arrangement ot the back lmember and the bevel on its upper portion aid in forming a member so arranged as to distort one end a left handed nut for locking the bolt of the band When engaged therewith to reagainst rotation. movably lock it to the coupling, a kerfed In testimony, that I claim the foregoing 10 winding bolt rotatably mounted in the side as my invention, I have signed my name 5 members, the kerf on said bolt being extendthis ninth day of April 1915.

ed into the body of the bolt to form a slot for receiving the other end of the band, and GUSTAVE L. HERZ..
